# Wizardry IV: Apple II disk and format investigation

> An investigation of the Apple II release of Wizardry IV uses SYSTEM.RELOC to map five disk sides into a virtual volume and examines the separate sixth side. It studies the game's p-machine program, Huffman text, level maps and leftover files, with purpose-built readers and saved command output supporting the format findings.
